Description
The Watts 0887541 2-Inch Second Check Repair Kit is a service component set intended for the second check section of a 009M2 backflow preventer assembly. The kit contains the parts required to service the check mechanism, allowing the internal flow-control components to be renewed without changing the complete valve body in HVAC systems. Positioned within the second check chamber, these parts work with the valve’s internal sealing and retention elements to control water movement through the assembly. The hydronic piping and water distribution systems, the second check mechanism assists maintain the required flow direction within the connected circuit.
